The Geminga radio pulsar. New low-frequency results

New detections of radio emission from the Geminga pulsar at three low radio frequencies are presented. The observations were carried out at 42–112 MHz on two sensitive transit radio telescopes of the Pushchino Radio Astronomy Observatory. Three new digital receivers were used to detect the pulses an...

description New detections of radio emission from the Geminga pulsar at three low radio frequencies are presented. The observations were carried out at 42–112 MHz on two sensitive transit radio telescopes of the Pushchino Radio Astronomy Observatory. Three new digital receivers were used to detect the pulses and obtain dynamical spectra. Examples of mean profiles and individual pulses of Geminga are presented. Dynamical spectra at these three frequencies are presented for the first time. The availability of simultaneous observations at three frequencies has made it possible to refine the pulsar’s dispersion measure.
